‘Call of Duty’ game frustrated a young dad, cops say. His 5-month-old ended up dead.

Other “Call of Duty” players were mocking him, he told police. One called him a “failure” at the first-person-shooter video game.

But Zion Shockley, 18, didn’t take his frustrations out on the other video game players. Instead, police said, his victim was his 5-month-old daughter, CBS reports. Angry over the game, Shockley tossed the infant into the air, but failed to catch her — multiple times, police said.

Shockley shook the baby violently as well, leaving her so injured that the infant was in cardiac arrest when police arrived at Shockley’s Coatsville, Pa., home on Feb. 10, prosecutors said. The girl was rushed to a nearby hospital, bleeding from her brain and eyes, with trauma caused by “both recent and ongoing abuse,” prosecutors said.

The infant, named Rosalie Faith Crothers-Shockley, died two days later.

“An infant can not defend herself. A baby can not run away or call for help,” Chester County District Attorney Tom Hogan said in a statement. “A baby is the most vulnerable and innocent victim possible. Now it is our job to do what this baby could not, and deliver justice to the killer.”

Shockley, who was the girl’s primary caretaker at the time of her death, has been charged with first-degree murder in the case, Chester County prosecutors announced this week.

He’s being held at Chester County Prison without bail, prosecutors said.

Police said that Shockley admitted to the Feb. 10 incident that killed the child, NBC Philadelphia reports, as well as to shaking the infant in anger over video games he was playing on his PlayStation 4 at some point around Christmas.

During the Feb. 10 abuse, Shockley shook the infant for about a minute, and eventually went downstairs for water, police said. But when he got back, the child wasn’t breathing, ABC 6 reports.

Custody of the child was shared with the child’s mother, NBC reports, but the suspect in her death was the girl’s caretaker when she sustained the fatal injuries, police said.

Hogan told CBS that the baby’s mother “did everything she could to care for the child.”

Other possible causes for the deadly injuries have been ruled out, Hogan said, adding that county investigators “have become highly skilled at differentiating accidents from intentionally inflicted injuries.”

“When the defendant was being mocked by players and his reaction was to severely injure and ultimately murder his own child,” Hogan told CBS. “That is someone who should not be in charge of a child to begin with.”
